The specific embodiment
Below in conjunction with accompanying drawing and by the specific embodiment, further illustrate technical scheme of the present invention.
Embodiment mono-
As shown in Figure 1, Figure 2 and shown in Fig. 3, be respectively front elevation, right elevation and the rear view (RV) of the elevator pit maintenance fender guard that provides in embodiment mono-.
A kind of elevator pit maintenance fender guard providing in the present embodiment; comprise hinge 1, sleeve 2, slide bar 3, positioning plate 4 and adapter plate 5; the first flap 11 of hinge 1 is fixedly connected with adapter plate 5; the mode being fixedly connected with is preferably bolt and connects; the second flap 12 of hinge 1 is fixedly connected with sleeve 2, and the mode being fixedly connected with is preferably and is welded to connect.
As shown in Figure 5, be the first birds-eye view of the positioning plate that provides in the present embodiment one.
Positioning plate 4 is provided with primary importance hole 41 and second place hole 42, slide bar 3 and sleeve 2 bearing fits, at slide bar 3, from second place hole 421, move to the process in primary importance hole 4, need first slide bar 3 up to be put forward to a bit of distance, then rotate hinge 1 and to slide bar 3, be positioned at the top in primary importance hole 4, finally slide bar 3 is inserted in primary importance hole 41.
When slide bar 3 is positioned at primary importance hole 41, slide bar 3 stops car descending of elevators, that is to say, now slide bar 3 is positioned at the below of lift car, descending even if lift car occurs, and in the descending process of car, also can encounter slide bar 3, thereby supported by slide bar 3, again because slide bar 3 Length Ratio maintainers' height wants high, therefore car cannot injure maintainer by a crashing object, thereby guarantee maintainer's life security.
When slide bar 3 is positioned at second place hole 42, slide bar 3 does not stop the descending of car, that is to say, now slide bar 3 is not positioned at the below of lift car, and the sidewall of close elevator pit, in the descending process of elevator, can not encounter slide bar 3, car can normally go downwards to the bottom of elevator pit.
Known from above-mentioned record, it is less that the elevator pit maintenance fender guard providing in the present embodiment forms member, is only 5 primary members, easy to use, takes up room little, practical.
Preferably, slide bar 3 is circular pin, square pole or triangular pelvis, corresponding also can be arranged to similar shape by primary importance hole 41 and second place hole 42, both guaranteed that slide bar 3 can insert primary importance hole 41 and second place hole 42, also guaranteed that 42 pairs of slide bars in primary importance hole 41 and second place hole 3 carried out suitable spacing.
Embodiment bis-
As shown in Figure 6, be the second birds-eye view of the positioning plate that provides in embodiment bis-.
A kind of elevator pit maintenance fender guard providing in the present embodiment; it is with the difference of embodiment mono-: primary importance hole 41 is connected by arc groove 43 with second place hole 42; hinge 1 is connected with driver train; driver train is connected with controller, and the infrared inductor on the access door of controller and elevator pit is connected.Driver train is used for driving hinge 1 open or close up.
When maintainer enters access door, infrared inductor detects infrared signal and sends controller to, controller sends control signal to driver train, drive configuration moves primary importance hole 41 by slide bar 2 by second place hole 42 by loose-leaf 1, thereby make slide bar 3 be positioned at the below of car, guarantee the maintainer's of elevator pit safety.
Merit attention and be, adopt infrared pickoff to detect in the process whether someone enters, need to be arranged side by side plural infrared pickoff, now two infrared pickoffs are that example is illustrated:
Two infrared pickoffs are the first infrared pickoff and the second infrared pickoff, if there is maintainer to enter access door, the first infrared pickoff is first bright, if there is maintainer to walk out access door, the second infrared pickoff is first bright, with Time Controller real time recording, pass in and out the personnel's of access door quantity, only have when elevator pit inside does not have maintainer, when the personnel's number entering deducts the personnel number of walking out and is zero, drive configuration just moves second place hole 42 by slide bar 2 by primary importance hole 41 by loose-leaf 1, and slide bar 3 no longer hinders the descending of lift car.
A kind of elevator pit providing in the present embodiment overhauls fender guard, has the function of automatic identification and judgement, and maintainer needn't overhaul fender guard to elevator pit and carry out any operation.
Embodiment tri-
As shown in Figure 4, be the block diagram of the elevator pit maintenance fender guard that provides in embodiment tri-.
A kind of elevator providing in the present embodiment, comprises that the inside of pit, pit is provided with the elevator pit maintenance fender guard in car guide rail 6 and the embodiment of at least one mono-or embodiment bis-.
Preferably, positioning plate 4 is fixed on the bottom of pit by swell fixture, and adapter plate 5 is fixed on the sidewall of pit by swell fixture, completes the installation of elevator pit maintenance fender guard.
Further preferred, car guide rail 6 is provided with presses guide plate 7, presses guide plate 7 to be fixedly connected with adapter plate 5 by tightening screw, and positioning plate 4 is fixed on the bottom of pit by swell fixture, complete the installation of elevator pit maintenance fender guard.
The present invention is described by preferred embodiment, and those skilled in the art know, without departing from the spirit and scope of the present invention, can carry out various changes or equivalence replacement to these features and embodiment.The present invention is not subject to the restriction of specific embodiment disclosed herein, and other embodiment that fall in the application's claim belong to the scope of protection of the invention.
